This study aimed to address the toxicological effects the type-2 diabetes drug, metformin has on wild fathead minnows (Pimephales promelas). Fathead minnow embryos and adults were exposed to metformin via in-lake mesocosm and their survival, development and growth was assessed. Exposures were...

Zooplankton and phytoplankton were collected during the 56-day metformin in-lake mesocosm exposure conducted Lake 114 at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in northern Ontario, Canada. Samples were collected three times throughout the...

This study will determine the toxic effect the pharmaceutical metformin has on an aquatic environment. Chronic exposures were conducted at Lake 114 located at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in Ontario, Canada. Three concentrations of...

The daily water temperature (°C) dataset is reconstructed using the air2stream model (Toffolon and Piccolroaz 2015) with i) air temperature from ~10 km resolution 1980-2018 Regional Deterministic Reforecast System, version 2.1 (Gasset et al. 2021) and ii) streamflow data from the Water Survey of...

As part of the research program on the aquatic ecotoxicology of nanomaterials, a study was carried out using the invertebrate Hydra vulgaris in order to determine the influence that the shape of nanoparticles (sphere, cube and prism) have on the toxic potential of silver nanoparticles. The...

The Canada Nature Fund for Aquatic Species at Risk (CNFASAR) is a contribution program that focuses on providing funding for recovery and threat mitigation activities in nine priority places and to address two marine threats to aquatic species at risk. The Priority Places and Marine Threats layer...

Ocean physical conditions in the Maritimes Region in 2019 were characterized by cooler surface temperatures, continued warmer bottom temperatures and weaker stratification compared to recent years. Deep nutrient inventories were lower than normal over most of the region, with the exception of the...

Canadian tides and water level station information, benchmarks, observed water level data, and tidal predictions. The Canadian tide and water level data archive presently holds water level observations reported from over a thousand stations, with the earliest dating back to 1848. The number of...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...
